There's a lot of new ground to cover, so I'm gonna focus on two things: Willow's relationship with Kennedy, and the issue of whether or not the writers changed the direction of her character arc in S6 with regards to how/why she went evil.
Willow's relationship with Kennedy is yet another example from the Buffyverse of the old adage 'opposites attract'. Yes, they are very different personality-wise, and Kennedy is completely different from any of Willow's previous partners (male or female), and therefore it might be easy to find fault with the relationship, but I personally think that one of the reasons that it works is that we as an audience don't need to understand the whys behind it. Willow picked who she picked, and that's just the way it is. There's no questioning of the relationship the way there was with the W/T relationship at first, which is pretty cool, IMO.
Now, on to the subject of whether or not the writers changed the direction of their arc in making Willow go bad. I've always believed - and have found quite a bit of evidence to support said belief - that there was in fact no change in the 'Dark Willow' arc. It was always about addiction; what DID change was the way that Willow's addiction to magic manifested itself. Yes, it started out being about the power and Willow having the magic as a way to distinguish herself and deal with her deep-set self-esteem issues before becoming much more about the 'high', but even that aspect of the whole arc didn't come entirely out of nowhere (a frequent complaint I've heard) since there were already inferences about magic being used for drug-like purposes; we'd just never before actually seen it. I'd also like to point something else out: Willow getting hooked on the more drug-like aspects of magic is far from OOC, as it seems a lot of people seem to believe, since it is only the latest manifestation of her trying to use magic to deal with heartbreak.
